Definitions

  • the invention relates to a delivery device for running threads, with a storage body, to which the thread runs in the circumferential direction and from which the thread is drawn off overhead and on which a certain adjustable number of thread turns is stored as a supply quantity between the feed point and the take-off point, the determination of the Thread windings is provided a light barrier which scans the outer surface of the storage body and controls the rotary drive for the thread feed.
  • the light barrier serving to control the drive of the storage body in such a way that there is always approximately a predetermined wrap supply on the storage body. If the thread take-off in the axial direction reaches an order of magnitude such that the amount of wrapping falls below a certain lower limit, the light barrier causes the storage body to increase in speed. Conversely, there is a slowdown in the speed or even a shutdown of the storage body when the winding reserve exceeds the determined maximum limit.
  • the delivery device therefore works essentially according to the start / stop principle. As a result, the thread to be stored is subject to an unfavorable tensile load. Furthermore, the load on the braking device of such delivery devices is considerable.
  • the object of the invention is based on the object of producing a delivery device of the type in question to be designed in a simple manner so that, in addition to equalizing the thread tension when the thread is applied to the storage body, the braking device is less stressed.
  • the light barrier extends over the entire memory length of the storage body. The more thread turns are applied to the storage body, the lower the reflected light intensity. This means that the speed of the storage body is reduced with increasing light intensity reduction.
  • the tension of the applied thread is evened out.
  • the light intensity measurement (amount of light) can be measured with the light barrier bar - integrated via this - or also over the period of time that elapses between darkening and response of a light barrier that only senses the thread windings on the take-off side.
  • the rotary drive only stops the storage body when the thread turns should extend over the entire length of the storage unit. However, this is a special case that hardly occurs in practice. Therefore, the braking device assigned to the delivery device is subject to only a small load, combined with a longer life expectancy of the delivery device.
  • the light intensity of the light barrier transmitter can be varied over the storage length. This can be done, for example, using a potentiometer. This makes it easy to change the supply quantity. So z. B. by increasing the light intensity, the number of thread turns and Increase take-up speed. On the other hand, a reduction in the light intensity means a decrease in the number of thread turns as a supply quantity and a decrease in the winding speed. Further variations can be achieved in that the light barrier transmitter is designed from light-emitting diodes which are arranged in rows next to one another and which emit light that is adjustable in their light intensity. It is therefore possible to increase the light intensity evenly on all transmitters.
  • the light intensity can also be individually amplified. It is advantageous if the light barrier bar is designed so that a light guide is provided which transports the light from one point on the circumference of the storage body to another point.
  • This light guide can consist of a block of glass or the like or of light guide fibers, which are held by a support.
  • the storage body has a support piece with light guide fibers, whose end faces lying next to one another in rows are exposed to the surface of the storage body, one end face of each optical fiber displacing the light barrier transmitter and the other end face in the circumferential direction of the storage body faces the light barrier receiver.
  • Modulated light is preferably used to switch off interference effects from daylight or the like.
  • the transmitter and receiver of the light barrier can therefore be arranged adjacent to one another.
  • a variant is characterized in that the end faces of the optical fibers lie in two adjacent rods which are adjustably assigned to the storage body in order to vary the outer surface of the storage body in the region of the thread winding point.
  • This version is of course a standing storage body. If the rods are displaced, the optical fibers are also moved. However, they still serve as a requirement for the winding supply to be applied and lead to the best measurement results.
  • the storage body is to circulate, several arc pieces are in the circumferential direction of the Provide storage body one behind the other in such a way that their distance from each other is smaller than the opening cone coming to the light barrier transmitter and receiver. For this reason, the connection between transmitter and receiver is maintained in every rotary position of the storage body via a piece of elbow.
  • Manufacturing advantages are that the support consists of two concentric to each other and the optical fibers between receiving boards.
  • the delivery device illustrated in FIGS. 1 to 4 has a flange-mounted on a housing 1, the rotary drive forming electric motor 2 or the like.
  • Whose motor shaft not shown in detail, is rotatably connected to a thread eyelet carrier 3.
  • the incoming thread F enters a central channel of the motor shaft and from there to the thread eyelet 4 of the thread eyelet carrier 3, which rotates in the direction of the arrow x shown in FIG. 2.
  • the rotary drive is associated with a braking device, which is not illustrated in detail, but is known in such delivery devices.
  • the motor shaft of the electric motor 2 is the carrier of a storage body 5.
  • a storage body 5 is a standing storage body.
  • it has a jacket wall 6 designed as a drum, which merges into an end wall 7 at the end of the delivery device on the discharge side.
  • the trigger-side end of the jacket wall 6 is overlapped by a spherical ring head surface 8.
  • the latter is assigned a brake ring 10 equipped with bristles 9, which in turn is seated on a bracket 11. It is attached to the housing 1 by means of an annular flange 12.
  • the end of the arm 11 facing the ring head surface 8 carries at a bend 13 a thread take-off eye 14 which is coaxial to the axis of the storage body 5 and is arranged at a distance in front of the ring head surface 8.
  • the end of the jacket wall 6 facing the thread eyelet carrier 3 merges into a conical widening 16 via an annular groove 15.
  • the pitch angle of this conical extension is approx. 45 °.
  • a parallel section 17 adjoins the conical extension 16 and is overlapped by the thread eyelet carrier 3.
  • the storage body 5 is assigned rods 18 arranged in the same angular distribution, which partly lie in grooves 19 of the jacket wall 6 and protrude beyond them.
  • the ends 22 of the rods 18 adjoining the angular groove 20 engage in slots 21 of the conical widening 16 extending from the grooves 19.
  • the rods are supported with these ends 22 on radially directed fingers 23 of an adjusting disk 24.
  • the rods 18 with the disk 24 and fingers 23 can be displaced simultaneously in the direction of the arrow illustrated in FIG. 3.
  • the latter is also accessible from the ring head surface 8.
  • An adjustment of the disc 24 in the direction of the arrow leads to a pivoting of the rods 18 about a pivot point located near the ring head surface. In both cases, the winding conditions in the area of the thread feed point are varied.
  • a light barrier strip 27 which extends over the entire length of the storage body 5 of the storage body 5.
  • the storage length in the exemplary embodiment is less than the length of the storage body 5 itself.
  • the light barrier strip can also extend over a shorter length.
  • the light barrier 27 has a housing 28. This is the carrier of a transmitter 29 and receiver 30 of the light barrier. Both the transmitter 29 and the receiver 30 extend axially parallel to the storage body 5.
  • the light barrier transmitter 29 has light-emitting diodes 31 which are arranged in rows next to one another and emit modulated light which can be adjusted in terms of their light intensity. Each light-emitting diode 31 is assigned a preferably separate sensor 32 of the light barrier receiver 30.
  • a reflector plate 33 is embedded in the jacket wall. The light coming from the transmitter 29 therefore reaches this reflector board 33 and is then directed to the receiver 30 of the light barrier.
  • the light intensity measured by the light barrier receiver 30 is initially relatively large, so that the rotary drive operates at an increased speed.
  • the light intensity measured by the light barrier receiver 30 decreases along with a reduction in the rotational speed of the rotary drive. Due to the constant thread draw-off, however, the light intensity increases again with a renewed increase in the speed of the thread eyelet carrier 3. It is therefore not necessary to stop the rotary drive completely. Tension leading to thread breakage. This avoids peaks.
  • the light response threshold is shifted along with it. This results in an increase in the speed associated with an increase in the thread supply on the storage body.
  • the storage body 5 now carries a support piece 34.
  • the latter is designed as an arc piece and consists of two concentric optical fibers 35 between the receiving plates 36 and 37.
  • aluminum can serve as the material for the plates 36, 37.
  • the light guide fibers 35 are arranged such that their end faces 35 ', 35 "lying next to one another in rows are exposed to the surface of the storage body.
  • One end face 35' of each optical fiber 35 is the light barrier transmitter 29 and the other end face 35" in the circumferential direction of the storage body 5 offset the light barrier receiver 30 facing.
  • the end sections of the curved piece are embedded in slots 18 'of two adjacent rods 18 in such a way that the end faces 35', 35 "end with the lateral surface of the rods 18. Accordingly, the end faces 35 ', 35" of the rods are displaced when the rods are adjusted Optical fibers 35.
